Reply #35: You seem to think technology is not a product of evolution.

Your eyeglass example is absurd (no offense intended), though I understand what you are driving at when you say:

the fact that we can correct poor eyeseight with glasses, contact lenses, or laser surgery is a usurpation of evolution in a strict sense.

Eyeglasses are no less natural technology than a bird nest. They serve our needs. And perhaps the people have poor eyesight possess some subtle genetic trait or intellectual quality that serves the species? If this trait were "weeded" out from the gene pool, it might prove detrimental to the species, and prove devolutionary.

Humans don't control evolution in the slightest, they only have their evolutionary impact, like everything else.
